My name is Steve, and I'm 15 years old. I am afraid of confrontation with almost anyone except my closest friends. I have terrible self-esteem. I'm 5'6 and weigh 159 lbs, which everyone tells me isn't that bad, but I always feel fat, and ugly to those around me. I feel like I'm lesser than other people, that are more popular than me. I often drift into fantasies and wish I were those people.
My best friend is also my cousin, who is considered a pretty cool guy. He always gets the girl and any girl friend I've ever had, I have the feeling they like him more than me. I idolize him to some degree and wish I were more like him physically. He's slender but muscular. Anytime I'm around him I feel jealous, upset, or sad whenever I'm around him, though it's not his fault. He's extremely supportive of me, and gives me compliments and is a great person in general.
I don't know if this is anxiety or what, but I need to know what's the matter with me. I just feel so insignificant and worthless. I don't know.
